Sleeping bags are
sold in different styles (mummy, rectangular
>, hooded,
and kids’
sleeping bags), for varying temperatures
(extreme weather, cold weather, three season, and warm weather
sleeping bags), and with many different insulations (synthetic
fibers and down fill). Sleeping bag insulations should be
considered when purchasing your next bag. Here are some commonly
used insulations and their benefits.
Slumberloft HQ
is a synthetic fiber composed of a 50% hollow core polyester
fiber joined with a 50% solid core polyester fiber. This
combination offers great warmth and loft. Examples of sleeping
bags with Slumberloft HQ are: Slumberjack -
Latitude, Long -20F/-29C and Slumberjack -
Lil’ Timber, Kids Bag +10F/-12C.
DuPont Hollofil® 808
is a synthetic fiber. Its hollow core is designed to trap more
air for greater warmth and loft. Examples of sleeping bags with
this insulation are: Coleman -
Crescent +15F/-9C and Coleman -
Mountain Lodge, King -5F/-21C.
DuPont Hollofil® II
is a synthetic fiber that features four hollow tunnels that run
throughout its length. With four compartments per fiber to trap
air, it typically provides even more warmth and compactibility
than Hollofil 808. An example of a sleeping bag with this
insulation is: Coleman
Exponent - Northbound +0F/-18C.
DuPont Thermolite® Extreme
is a high performance insulation that blends three different
fibers - fine denier fibers, thermal bonding fibers, and hollow
core spring fibers. This tri-blend fiber system offers ultimate
warmth and superior compactibility. Examples of sleeping bags
with this insulation are: Slumberjack -
Diablo +40F/+4C and Slumberjack -
Odyssey, Long +10F/-12C.
DuPont Thermolite® Extra
is a high-loft, high-resilient technical insulation for
extraordinary warmth. Because it is made from unique patented
hollow-core, three-dimensional crimp having a helical
configuration, it provides superior loft, compactness, and
exceptional resiliency. An example of a sleeping bag with this
insulation is: Slumberjack -
Telluride, Long +30F/-1C.
Polarguard® HV
is a high-performance insulation made of high-void,
continuous-length polyester filaments that are bonded into a
batting of multiple layers. Because it is a continuous filament,
Polarguard HV does not shift, clump, or separate. An example of
a sleeping bag with this insulation is: Coleman
Exponent - Boulder Ridge +20F/-7C.
Polarguard® 3D
is a high performance insulation produced from continuous
filament in the same manner but finer than Polarguard HV. This
makes Polarguard 3D softer, more compressible and stronger while
providing great insulating value and loft. Examples of sleeping
bags with this insulation are: Sierra Designs
- Paul Bunyan, Long +10F/-12C and Sierra Designs
- Rosa, Regular +20F/-7C - Women’s sleeping bag.
Polarguard® Delta
continuous filament polyester is the newest member of the
Polarguard family. Polarguard Delta combines a super void cross
section with modified batt formation. The larger void creates
higher loft with less weight, making it warmer, yet lighter. An
example of a sleeping bag with this insulation is: Sierra Designs
- LX, Regular +45F/+7C.
Down
is a time honored, expedition proven natural insulation made of
very small extremely light down plumules found next to the skin
of geese. For its weight, down has an exceptional ability to
trap air, making it the most efficient warmth to weight
insulation available. Examples of sleeping bags with this
insulation are: Kelty - Light
Year Down, Long +15F/-9C and The Backside -
Blue Ice -50F/-46C (750 Down).
ThermoTech
exclusive to Coleman, is made of solid-core fibers and is soft
and lofty with good thermal retention, properties to keep
campers warm. Generally used for mild condition bags, this
insulation keeps campers snug on cool summer nights. Made of 100
percent polyester fibers, which are non-allergenic, machine
washable, and odorless. Examples of sleeping bags with this
insulation are: Coleman for
Kids - Journey Junior +40F/+4C and Coleman for
Kids - Voyager +40F/+4C.
Coletherm
also exclusive to Coleman, is a hollow-core fiber, allowing for
greater loft (a measure of the amount of space the insulation
occupies and the amount of air the insulation can trap). The
hollow-core fibers create pockets of air that serve as an extra
barrier between the sleeper and the environment, maximizing
thermal efficiency. Made of 100 percent polyester fibers, which
are non-allergenic, machine washable, and odorless. An example
of a sleeping bag with this insulation is: Coleman
Exponent - Big Basin +0F/-18C.
Buckloft®
is a fine denier, solid core polyester fiber. This combination
offers outstanding warmth with extra loft. An example of a
sleeping bag with this insulation is: Slumberjack -
Kenai +0F/-18C.
Buckloft HQ®
is a synthetic fiber composed of a 25% siliconized, hollow-core
polyester fiber joined with a 75% solid core polyester fiber.
This combination offers great warmth and comfort. An example of
a sleeping bag with this insulation is: Slumberjack -
Chaparral -30F/-34C.
Kelty CloudLoft®
is Kelty’s affordable and durable branded synthetic fill
insulation. The blend of solid core and hollow core fibers trap
heat efficiently and provide excellent loft and comfort.
Cloudloft is used in Kelty’s most value-oriented mummy and
rectangular bags. An example of a sleeping bag with this
insulation is: Kelty -
Mistral, Long +20F/-7C.
